Abstract excerpt

Retrospective chart review of 72 adult psychiatric patients receiving CBD as adjunctive treatment in an outpatient setting. Anxiety scores decreased in the first month for 79.2% of patients and remained decreased at month 3. Sleep scores improved within the first month for 66.7% of patients but fluctuated over time. CBD was generally well-tolerated; only 3 patients discontinued due to side effects. Findings are consistent with prior preclinical evidence and warrant controlled investigation.

Joe's notes

How to read this paper

Frequently cited in CBD wellness marketing — read the methodology. It's a chart review (not a controlled trial), open-label, with all the caveats that apply to that design. Real signal worth taking seriously, real limits worth respecting.
